Analysis of Organotins Using Large Volume Injection Gas Chromatography-Mass Spectrometry Selected Ion Monitoring
This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations.
Organotins have been used in the shipping industry as protective paint coatings applied to the hulls of ships. However, trisubstituted organotin compounds decompose in water in a stepwise manner to less substituted compounds, down to inorganic tin. As a result of their toxicity at low concentrations, trisubstituted organotin compounds are regulated through global environmental quality standards. To ensure regulatory compliance and environmental protection, the industry must perform rigorous monitoring of these compounds. This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations. An application example will be used to demonstrate the analytical capabilities of large volume injection gas chromatography-mass spectrometry selected ion monitoring (LVI GC–MS SIM) for analysing organotins.
Using Chromatography to Study Microplastics in Food: An Interview with Jose Bernal
December 16th 2024LCGC International sat down with Jose Bernal to discuss his latest research in using pyrolysis gas chromatography–mass spectrometry (Py-GC–MS) and other chromatographic techniques in studying microplastics in food analysis.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.
